TROPICAL STORM FABIO DISCUSSION NUMBER 6
NATIONAL WEATHER SERVICE MIAMI FL
2 PM PDT FRI AUG 04 2000
STRONG NORTHEASTERLY SHEAR HAS ONCE AGAIN REMOVED MOST OF THE
CONVECTION FROM THE LOW-LEVEL CENTER. THIS MEANS THAT FABIO HAS NOT
INTENSIFIED AS EXPECTED AND...IN FACT...IT COULD BE WEAKER THAT
EARLIER TODAY. NO SIGNIFICANT CHANGE IN STRENGTH IS INDICATED IN
THE FORECAST AT THIS TIME. HOWEVER...SINCE THE OCEAN IS WARM...ANY
RELAXATION OF THE SHEAR WOULD RESULT IN AN INTENSIFICATION OF THE
STORM.
A STRONG SUBTROPICAL RIDGE NORTH OF FABIO IS FORECAST TO STRENGTHEN
AND BUILD WESTWARD. THIS PATTERN WILL KEEP FABIO ON A GENERAL
WESTWARD OR EVEN SOUTH OF DUE WEST TRACK. THIS IS CONSISTENT WITH
MOST OF THE TRACK MODELS.
